thanks 'TenaciousJ' for those links on where to get dry dat head cleaning tapes. I'm sure that somewhere on the web I could find a step by step on how to manually clean the heads for my dat recorder, and if all else fails when i start to notice any errors on my tapes i could send it in then. On there website ProDigital say's that there is a normal service and diagnosis fee, if the machine is beyond repair they will wave the fee. It seems that worst case senario could cost me up to $400.(i paid less for my dat) but they also sell used refurbished units for around the same price.has anyone taken there Sony PCM-M1 apart to clean the heads? is this a hard task or is it better to try without removing the cassette door?
